# Authentication
|
||
|
||
## LDAP (Lightweight Directory Access Protocol)
|
||
|
||
Both the LDAP via BindDN and the simple auth LDAP share the following fields:
|
||
|
||
- Authorization Name **(required)**
|
||
- A name to assign to the new method of authorization.
|
||
|
||
- Host **(required)**
|
||
- The address where the LDAP server can be reached.
|
||
- Example: `mydomain.com`
|
||
|
||
- Port **(required)**
|
||
- The port to use when connecting to the server.
|
||
- Example: `389` for LDAP or `636` for LDAP SSL
|
||
|
||
- Enable TLS Encryption (optional)
|
||
- Whether to use TLS when connecting to the LDAP server.
|
||
|
||
- Admin Filter (optional)
|
||
- An LDAP filter specifying if a user should be given administrator
|
||
privileges. If a user account passes the filter, the user will be
|
||
privileged as an administrator.
|
||
- Example: `(objectClass=adminAccount)`
|
||
- Example for Microsoft Active Directory (AD): `(memberOf=CN=admin-group,OU=example,DC=example,DC=org)`
|
||
|
||
- Username attribute (optional)
|
||
- The attribute of the user's LDAP record containing the user name. Given
|
||
attribute value will be used for new Gitea account user name after first
|
||
successful sign-in. Leave empty to use login name given on sign-in form.
|
||
- This is useful when supplied login name is matched against multiple
|
||
attributes, but only single specific attribute should be used for Gitea
|
||
account name, see "User Filter".
|
||
- Example: `uid`
|
||
- Example for Microsoft Active Directory (AD): `sAMAccountName`
|
||
|
||
- First name attribute (optional)
|
||
- The attribute of the user's LDAP record containing the user's first name.
|
||
This will be used to populate their account information.
|
||
- Example: `givenName`
|
||
|
||
- Surname attribute (optional)
|
||
- The attribute of the user's LDAP record containing the user's surname.
|
||
This will be used to populate their account information.
|
||
- Example: `sn`
|
||
|
||
- E-mail attribute **(required)**
|
||
- The attribute of the user's LDAP record containing the user's email
|
||
address. This will be used to populate their account information.
|
||
- Example: `mail`
|
||
|
||
**LDAP via BindDN** adds the following fields:
|
||
|
||
- Bind DN (optional)
|
||
- The DN to bind to the LDAP server with when searching for the user. This
|
||
may be left blank to perform an anonymous search.
|
||
- Example: `cn=Search,dc=mydomain,dc=com`
|
||
|
||
- Bind Password (optional)
|
||
- The password for the Bind DN specified above, if any. _Note: The password
|
||
is stored in plaintext at the server. As such, ensure that your Bind DN
|
||
has as few privileges as possible._
|
||
|
||
- User Search Base **(required)**
|
||
- The LDAP base at which user accounts will be searched for.
|
||
- Example: `ou=Users,dc=mydomain,dc=com`
|
||
|
||
- User Filter **(required)**
|
||
- An LDAP filter declaring how to find the user record that is attempting to
|
||
authenticate. The `%s` matching parameter will be substituted with login
|
||
name given on sign-in form.
|
||
- Example: `(&(objectClass=posixAccount)(uid=%s))`
|
||
- Example for Microsoft Active Directory (AD): `(&(objectCategory=Person)(memberOf=CN=user-group,OU=example,DC=example,DC=org)(sAMAccountName=%s)(!(UserAccountControl:1.2.840.113556.1.4.803:=2)))`
|
||
- To substitute more than once `%[1]s` should be used instead, e.g. when
|
||
matching supplied login name against multiple attributes such as user
|
||
identifier, email or even phone number.
|
||
- Example: `(&(objectClass=Person)(|(uid=%[1]s)(mail=%[1]s)(mobile=%[1]s)))`
|
||
|
||
**LDAP using simple auth** adds the following fields:
|
||
|
||
- User DN **(required)**
|
||
- A template to use as the user's DN. The `%s` matching parameter will be substituted with login name given on sign-in form.
|
||
- Example: `cn=%s,ou=Users,dc=mydomain,dc=com`
|
||
- Example: `uid=%s,ou=Users,dc=mydomain,dc=com`
|
||
|
||
- User Filter **(required)**
|
||
- An LDAP filter declaring when a user should be allowed to log in. The `%s`
|
||
matching parameter will be substituted with login name given on sign-in
|
||
form.
|
||
- Example: `(&(objectClass=posixAccount)(cn=%s))`
|
||
- Example: `(&(objectClass=posixAccount)(uid=%s))`
|
||
|
||
**Verify group membership in LDAP** uses the following fields:
|
||
|
||
* Group Search Base (optional)
|
||
* The LDAP DN used for groups.
|
||
* Example: `ou=group,dc=mydomain,dc=com`
|
||
|
||
* Group Name Filter (optional)
|
||
* An LDAP filter declaring how to find valid groups in the above DN.
|
||
* Example: `(|(cn=gitea_users)(cn=admins))`
|
||
|
||
* User Attribute in Group (optional)
|
||
* Which user LDAP attribute is listed in the group.
|
||
* Example: `uid`
|
||
|
||
* Group Attribute for User (optional)
|
||
* Which group LDAP attribute contains an array above user attribute names.
|
||
* Example: `memberUid`
|
||
|
||
## PAM (Pluggable Authentication Module)
|
||
|
||
To configure this you just need to set the 'PAM Service Name' to a filename in `/etc/pam.d/`.
|
||
If you want it to work with normal Linux passwords, the user running Gitea must have read access to `/etc/shadow`.
|
||
|
||
## SMTP (Simple Mail Transfer Protocol)
|
||
|
||
This option allows Gitea to log in to your SMTP host as a Gitea user. To configure this, simply set the fields below:
|
||
|
||
- Authentication Name **(required)**
|
||
- A name to assign to the new method of authorization.
|
||
|
||
- SMTP Authentication Type **(required)**
|
||
- Type of authentication for use on your SMTP host, PLAIN or LOGIN.
|
||
|
||
- Host **(required)**
|
||
- The address where the SMTP host can be reached.
|
||
- Example: `smtp.mydomain.com`
|
||
|
||
- Port **(required)**
|
||
- The port to use when connecting to the server.
|
||
- Example: `587`
|
||
|
||
- Allowed Domains
|
||
- Restrict what domains can log in if you're using public SMTP host or SMTP host with multiple domains.
|
||
- Example: `gitea.io,mydomain.com,mydomain2.com`
|
||
|
||
- Enable TLS Encryption
|
||
- Enable TLS encryption on authentication.
|
||
|
||
- Skip TLS Verify
|
||
- Disable TLS verify on authentication.
|
||
|
||
- This authentication is activate
|
||
- Enable or disable this auth.
|
||
|
||
## FreeIPA
|
||
|
||
- In order to log in to Gitea using FreeIPA credentials, you need to create a bind account for Gitea to use:
|
||
|
||
- On the FreeIPA server, create a `gitea.ldif` file, replacing `dc=example,dc=com` with your DN, and providing an appropriately secure password:
|
||
```
|
||
dn: uid=gitea,cn=sysaccounts,cn=etc,dc=example,dc=com
|
||
changetype: add
|
||
objectclass: account
|
||
objectclass: simplesecurityobject
|
||
uid: gitea
|
||
userPassword: secure password
|
||
passwordExpirationTime: 20380119031407Z
|
||
nsIdleTimeout: 0
|
||
```
|
||
|
||
- Import the LDIF (change localhost to an IPA server if needed), you’ll be prompted for your Directory Manager password:
|
||
```
|
||
ldapmodify -h localhost -p 389 -x -D \
|
||
"cn=Directory Manager" -W -f gitea.ldif
|
||
```
|
||
- Add an IPA group for gitea_users :
|
||
```
|
||
ipa group-add --desc="Gitea Users" gitea_users
|
||
```
|
||
- Note: If you get an error about IPA credentials, please run `kinit admin` and give your admin account password.
|
||
|
||
- Now login to the Gitea as an Administrator, click on "Authentication" under Admin Panel. Then click `Add New Source` and fill in the details, changing all where appropriate to your own domain.
